A spectacular nighttime blastoff lit up the evening skies for hundreds of miles around the Florida Space coast on a mission that sent a critical NASA communications relay satellite to orbit this evening, Jan. 23.

NASA’s huge Tracking and Data Relay Satellite L (TDRS-L) is now safely in orbit following tonight’s successful launch aboard a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station in Florida.

The Atlas V rocket was launched at 9:33 p.m. EST from Space Launch Complex 41 into crystal clear skies that gave excited spectators an uncommonly long and stunning launch spectacle that was well worth the wait.

The 3.8 ton TDRS-L satellite will become part of a network providing high-data-rate communications to the International Space Station (ISS), Hubble Space Telescope, launch vehicles and a host of other research spacecraft that relay absolutely critical flight, telemetry and science data.

The recently launched Orbital Sciences Cygnus cargo carrier also relays data via the TDRS system.

The ISS, Hubble and all these other spacecraft could not function without the TDRS network of relay satellites.

The TDRS-L satellite will also be used to track and relay vital information for the maiden launch of NASA’s next generation Orion human spaceflight capsule slated for Fall 2014.

“TDRS-L and the entire TDRS fleet provide a vital service to America’s space program by supporting missions that range from Earth-observation to deep space discoveries,” said NASA Administrator Charles Bolden.

“TDRS also will support the first test of NASA’s new deep space spacecraft, the Orion crew module, in September. This test will see Orion travel farther into space than any human spacecraft has gone in more than 40 years.”

TDRS-L arrived in geosynchronous transfer orbit about two hours after liftoff. It will orbit at an altitude of 22,300 miles.

The venerable Atlas V rocket is one of the most reliable and well built rockets in the world.

Indeed the Atlas V has been entrusted to launch many high value missions for NASA and the Defense Department- such as Curiosity, JUNO and the X-37 B.

The last Atlas V launch from the Cape occurred in November 2013 and sent NASA’s MAVEN Mars orbiter on a voyage to the Red Planet.

And the two stage rocket is being man-rated right now to launch humans to low Earth orbit in the near future.

The Atlas V has been chosen to launch two of the upcoming astronaut ‘space taxis’ as part of NASA’s commercial crew initiative to launch human crews to the International Space Station.

Just today, Sierra Nevada Corp announced that their Dream Chaser mini shuttle will launch to orbit on its first flight on Nov. 1, 2016.

TDRS-L is the 12th in this series of communications satellites.

It is identical to the TDRS-K spacecraft launched in 2013, which was the first of the third generation of TDRS satellites.

They were built by Boeing Space and Intelligence Systems of El Segundo, Calif., and have a 15 year design lifetime.

NASA will now conduct a three month in orbit checkout.

TDRS-M, the next spacecraft in this series, is on track to be ready for launch in late 2015.

This is the third generation of TDRS satellites.

“The TDRS fleet began operating during the space shuttle era with the launch of TDRS-1 in 1983. Of the 11 TDRS spacecraft placed in service to date, eight still are operational. Four of the eight have exceeded their design life,” said NASA.

The Atlas V launched in the 401 configuration vehicle, which includes a 4-meter diameter payload fairing and no solid rocket motors. The first stage was powered by the RD AMROSS RD-180 engine. The Centaur upper stage was powered by a single Aerojet Rocketdyne RL10A-4 engine.

Opportunity Discovers That Oldest Rocks Reveal Best Chance for Martian Life

After a decade of roving relentlessly on the Red Planet, NASA’s Opportunity rover discovered rocks that preserve the best evidence yet that ancient Mars was the most conducive time period for the formation of life on our Solar System’s most Earth-like Planet, according to the science leaders of the mission.

Opportunity found the rocks – laden with clay minerals – barely over half a year ago in the spring of 2013, at an outcrop named ‘Whitewater Lake’ along an eroded segment of a vast crater named Endeavour that spans some 22 kilometers (14 miles) in diameter.

“These rocks are older than any we examined earlier in the mission, and they reveal more favorable conditions for microbial life than any evidence previously examined by investigations with Opportunity,” says Opportunity Deputy Principal Investigator Ray Arvidson, a professor at Washington University in St. Louis.

Opportunity investigated the rocks at a spot dubbed Matejivic Hill where researchers believe iron-rich smectite was produced in an aqueous environment some 4 billion years ago that was relatively benign and with a nearly neutral pH – thus offering potential life forms a habitable zone with a far better chance to originate and thrive for perhaps as long as hundreds of millions of years.

The new scientific findings are being published in the journal Science on Jan. 24, which just happens to exactly coincide with Opportunity’s landing on the Red Planet ten years ago at Meridiani Planum.

Matejivic Hill is located on the Cape York rim segment of Endeavour crater. See locations on our Opportunity route map below.

“The punch line here is that the oldest rocks Opportunity has examined were formed under very mild conditions — conditions that would have been a much better niche for life, and also much better for the preservation of organic materials that would have been produced,” said Arvidson at a NASA media briefing today, Jan. 23.

Opportunity rover discovered phyllosilicate clay minerals and calcium sulfate veins at the bright outcrops of ‘Whitewater Lake’, at right, imaged by the Navcam camera on Sol 3197 (Jan. 20, 2013, coinciding with her 9th anniversary on Mars. “Copper Cliff” is the dark outcrop, at top center.

Immediately after landing on Mars on Jan.24, 2004 inside Eagle crater, the six wheeled robot found rocks within her eyesight that provided concrete evidence that eons ago Mars was much warmer and wetter compared to the cold, arid conditions that exist today.

Although those sulfate rich rocks proved that liquid water once flowed on the surface of the Red Planet, they also stem from a time period with a rather harsh environment that was extremely acidic, containing significant levels of sulfuric acid that would not be friendly to the formation or sustainability of potential Martian life forms.

“Evidence is thus preserved for water-rock interactions of the aqueous environments of slightly acidic to circum-neutral pH that would have been more favorable for prebiotic chemistry and microorganisms than those recorded by younger sulfate-rich rocks at Meridiani Planum,” Ardivson wrote in the Science paper, of which he is the lead author, along with many other team members.

The science team directed Opportunity to Matejivic Hill and the ‘Whitewater Lake’ area of outcrops based on predictions from spectral observations collected from the CRISM spectrometer aboard one of NASA’s spacecraft circling overhead the Red Planet – the powerful Mars Reconnaissance Orbiter (MRO).

Opportunity arrived at Mars barely 3 weeks after her twin sister, Spirit on 3 January 2004.

The long lived robot has been methodically exploring along the rim of Endeavour crater since arriving in August 2011.

The newly published results from Opportunity correlate very well with those from sister rover Curiosity which likewise found a habitable zone where drinkable water once flowed on the opposite side of Mars.

The combined discoveries from the golf cart sized Opportunity and the SUV sized Curiosity tell us that the presence of liquid water was widespread on ancient Mars.

“The more we explore Mars, the more interesting it becomes. These latest findings present yet another kind of gift that just happens to coincide with Opportunity’s 10th anniversary on Mars,” said Michael Meyer, lead scientist for NASA’s Mars Exploration Program.

“We’re finding more places where Mars reveals a warmer and wetter planet in its history. This gives us greater incentive to continue seeking evidence of past life on Mars.”

Opportunity is currently investigating a new cache of clay mineral outcrops by the summit of Solander Point, a rim segment just south of Cape York and Matejivic Hill.

These outcrops were likewise detected by the CRISM spectrometer aboard MRO. The hunt for these outcrops was detailed in earlier discussions I had with Ray Arvidson.

Today marks Opportunity’s 3555th Sol or Martian Day roving Mars – for what was expected to be only a 90 Sol mission.

So far she has snapped over 188,200 amazing images on the first overland expedition across the Red Planet.

Her total odometry stands at over 24.07 miles (38.73 kilometers) since touchdown on Jan. 24, 2004 at Meridiani Planum.

Meanwhile on the opposite side of Mars, Opportunity’s younger sister rover Curiosity is trekking towards gigantic Mount Sharp. She celebrated 500 Sols on Mars on New Years Day 2014.

And a pair of new orbiters are streaking to the Red Planet to fortify the Terran fleet- NASA’s MAVEN and India’s MOM.

Finally, China’s Yutu rover is trundling across pitted moonscapes.

Sierra Nevada Dreamchaser Will Launch on First Orbital Flight Test in November 2016

Commercial space company Sierra Nevada Corporation and NASA announced plans today to launch an orbital test flight of the Dream Chaser vehicle in 2016, and that they plan to use processing facilities at Kennedy Space Center as well as land the vehicle at NASA’s Shuttle Landing Facility in Florida.

“Today we’re very proud to announce that we have now formally negotiated our orbital spaceflight,” said Mark Sirangelo, the head of Sierra Nevada Space Systems. “We have acquired an Atlas V rocket and established a launch date of November 1, 2016, so in a little over two years from now and we’re going to be taking our vehicle to space on the board one of the best rockets that has ever been designed, the Atlas V.”

The mission will be automated and unmanned, but if all goes well Sierra Nevada hopes to have a human flight by sometime in 2017.

The seven-passenger vehicle looks like a mini-space shuttle and is about 9 meters long (29.5 feet) with a wingspan of 7 meters (22.9 feet).

Sirangelo said they will be doing Dream Chaser pre- and post-flight processing at KSC along with Lockheed Martin at the Operations and Checkout (O&C) facility at KSC. The O&C is an historic facility which was originally built to process Gemini and Apollo era spacecraft. After significant upgrades by NASA and the State of Florida, it is currently being used by Lockheed Martin Space Systems to develop, assemble and test NASA’s Orion spacecraft.

The 2017 flights will be the first time an Atlas V will be used to send people to space since the Mercury program. The landing at the SLF will be the first landing of a space vehicle there since the final space shuttle mission, STS-135, landed there on July 21, 2011.

“That is way too long (between landings),” said Steve Lindsey, former NASA astronaut and now Sierra Nevada’s Dream Chaser program manager, “and we intend to do something about it and do it very soon… We want to continue the long tradition that was started on the Florida space coast so many years ago.”

During a question and answer period with media, questions were asked about which entity is paying for which portions of the launch and processing. But the officials were coy about not answering those questions directly.

Officials from NASA, Sierra Nevada, Lockheed Martin, United Launch Alliance and Space Florida took part in the announcement, which you can watch below.

“Today’s announcement confirms the faith the commercial industry has in Kennedy Space Center,” said Bob Cabana, the director of Kennedy Space Center.

The Dream Chaser had a test landing in October, 2013 after it was hoisted in the air by a helicopter. The automated landing went well except that one of the landing gears failed to deploy properly.

Sierra Nevada announced last week that they had completed their latest milestone for the NASA’s commercial crew program, the Commercial Crew Integrated Capability (CCiCap), Milestone 7, which is the Certification Plan Review for the entire Dream Chaser Space System. They delivered nearly 6,000 pages of technical documentation on the strategy, verification, and validation of Dream Chaser and its integration with the Atlas V launch vehicle and ground mission control systems.

Black Hole Steals Gas From Trillions Of Stars

Got gas? The black hole in galaxy cluster RX J1532.9+3021 is keeping it all for itself and stopping trillions of stars from coming to be, according to new research. You can see data above from NASA’s Chandra X-ray Observatory (purple) and the Hubble Space Telescope (yellow).

The drama is taking place about 3.9 billion light-years from Earth, showing an extreme phenomenon that has been noted in other galaxies on smaller scales, Chandra officials stated.

“The large amount of hot gas near the center of the cluster presents a puzzle,” a statement read. “Hot gas glowing with X-rays should cool, and the dense gas in the center of the cluster should cool the fastest. The pressure in this cool central gas is then expected to drop, causing gas further out to sink in towards the galaxy, forming trillions of stars along the way. However, astronomers have found no such evidence for this burst of stars forming at the center of this cluster.”

What’s blocking the stars (according to data from Chandra and the National Science Foundation’s Karl G. Jansky Very Large Array) could be supersonic jets blasting from the black hole and shoving the gas in the area away, forming cavities on either side of the galaxy. These cavities, by the way, are immense — at 100,000 light-years across each, this makes them about as wide as our home galaxy, the Milky Way.

The big question is where that power came from. Perhaps the black hole is “ultramassive” (10 billion times of the sun) and has ample mass to shoot out those jets without eating itself up and producing radiation. Or, the black hole could be smaller (a billion times that of the sun) but spinning quickly, which would allow it to send out those jets.

You can find more details in a November 2013 paper from The Astrophysical Journal (also available in a prepublished version on Arxiv.) The research was led by Julie Hlavacek-Larrondo from Stanford University.

Will Spacewalks Happen On Expedition 40? NASA Undecided Due To Leak Investigation

Remember those snorkels and pads astronauts used during the ammonia pump replacement on station this past December? The new measures went a long way to helping astronauts stay safe if another helmet water leak happens, but at the same time, NASA is eager to find the cause so they know how it happened and how to prevent it.

Two maintenance spacewalks are planned for Expedition 40, but they’re not necessarily going forward yet. NASA has traced the issue to a fan pump separator, but there’s another issue, explained expedition commander Steve Swanson: where the particulates in the water came from. Perhaps they were from a filter, or perhaps from the water system itself. So NASA is reserving spacewalks on a need-only basis until more is known.

“That was the problem. Now, we’ve got to find out where that came from,” Swanson said in a phone interview with Universe Today from Houston to preview Expedition 39/40’s mission, which launches in late March. Joining the two-time shuttle astronaut will be two other people, including Alexander Skvortsov. The Russian cosmonaut commanded Expedition 24 in 2010, which experienced a similar ammonia leak to the one that was just repaired a few months ago.

While leaks and spacewalks are the items that grab headlines when it comes to spaceflight, one of the major goals of the International Space Station is more subtle. Researchers hope to understand how spaceflight affects the human body during long-duration missions. (This will be a major focus of a one-year mission to station in 2015.) Through a translator, Skvortsov explained that the recent decision to extend station’s operations to at least 2024 will be a help for research of this kind.

“It is great that they have expanded the station until 2024 at least, and it will be very beneficial to the science programs and projects we have on board,” he said in Russian. “I hope that it will be extended even further. It will depend on the condition of the station.”

Rounding out the crew will be Oleg Artemyev, a first-time cosmonaut who has participated in precursor isolation experiments to the Mars 500 mission that saw a crew of people simulate a mission to Mars.

Expedition 39 is expected to launch March 26, 2014 from the Baikonour Cosmodrome in Kazakhstan. The crew will join orbiting spacefarers Koichi Wakata (who will command Expedition 39, a first for Japan), Rick Mastracchio (who participated in the ammonia pump swap-out) and Mikhail Tyurin.

Astrophotographers Rush to Capture Images of New Supernova 2014J

With news yesterday of the closest confirmed type Ia supernova since the 1800’s, astronomers in the northern hemisphere risked frostbite and hoped for clear skies to try and capture images of the newly named supernova, 2014J.

Others quickly sorted through images taken of the galaxy M82 taken within the last week to see if they managed to capture it unknowingly! Currently at about +11.5 magnitude, you’ll need at least a 4-inch and larger telescope to see SN2014J. But it is not hard to see in these great images here, as the object is the only bright star shining in the galaxy. Of course, not all of us have access to equipment like the 32-inch telescope at the Mount Lemmon Sky Center, but Adam Block stayed up for most of the night and managed to capture this spectacular image of M82 and the supernova.

See below for more:

This is one example of astronomers looking back at recent images to see if they captured the supernova without knowing it. This one by Sarah Hall and Colin Campbell was taken on January 19, 2014 between 20:39 to 20:44 UTC with a Newtonian Telescope with prime focus DSLR observation, 8 inch aperture 1000mm focal length (f/5).

The buzz on Twitter has been that the supernova was so bright, that automated supernova search telescopes and programs missed it because it was too bright and they dismissed it as an anomaly.

One of the latest Astronomer Telegrams puts the star going supernova no earlier than January 11 and sometime prior to January 19, but they haven’t narrowed it down any further yet. I’m sure more images will surface to help pinpoint the time.

In the meantime, enjoy these other great shots:

Dusty, Windy And Damp: Five NASA Probes To Hunt Down Climate Change in 2014

How badly will climate change affect our planet? Different models tell us different things, and that’s partly because we need more precise information about the factors that warm the world. How much is sea level rising? What are the levels of carbon dioxide in the atmosphere? All of these things must be known.

NASA expects to launch five Earth science missions this year, which is the biggest roster in more than a decade. They’ll track rainfall, seek water hiding in soil, and examine carbon dioxide and ocean winds around the world. Here’s a quick rundown of the busy launch schedule:

Global Precipitation Measurement (GPM) Core Observatory (Feb. 27): This will be the first of a series of satellites to look at snow and rain from space. “This new information will help answer questions about our planet’s life-sustaining water cycle, and improve water resource management and weather forecasting,” NASA stated. This joint spacecraft with the Japanese Aerospace Exploration Agency (JAXA) will launch from Japan’s Tanegashima Space Center on a H-IIA rocket. GPM was built at NASA’s Goddard Space Flight Center in Maryland.

ISS-RapidScat (June 6): This sensor will sit on the International Space Station and monitor ocean winds (including storms and hurricanes). What’s interesting about this mission is its use of old parts, NASA points out, as well as the decision to mount it on a station rather than take the more expensive route of making it a separate satellite. The probe will launch on a SpaceX Dragon spacecraft (aboard a SpaceX Falcon 9 rocket) from Florida’s Cape Canaveral Air Force Station as part of a regular commercial resupply flight.

Orbiting Carbon Observatory (OCO)-2 (July): NASA plans to take a second crack at this type of satellite after the OCO launch failure in 2009. The satellite will seek out carbon dioxide to better understand where it is emitted (in both natural and artificial processes) and how it moves through the water, air and land. This will launch from California’s Vandenberg Air Force Base on a Delta II rocket. OCO-2 will be managed by NASA’s Jet Propulsion Laboratory in California.

Cloud-Aerosol Transport System (CATS) (Sept. 12): This technology demonstration project will use lasers, in three wavelengths, to examine tiny particles borne into the atmosphere from phenomena such as pollution, smoke, dust and volcanoes. “These aerosol particles pose human health risks at ground level and influence global climate through their impact on cloud cover and solar radiation in Earth’s atmosphere,” NASA stated. This will also leave Earth aboard a SpaceX resupply flight from Cape Canaveral.

Soil Moisture Active Passive (SMAP) mission (November): Will check out the moisture level of soil, with the aim of refining “predictions of agricultural productivity, weather and climate,” NASA stated. Also managed by JPL, this satellite will spend its time in an almost-polar “sun-synchronous” orbit that keeps the sun’s illumination below constant during SMAP’s turns around the Earth. SMAP will launch from Vandenberg on a Delta II rocket.

Watch: An Amazing, Mesmerizing Full Rotation of Jupiter

Jupiter as imaged by Michael Phillips on July 25th, 2009... note the impact scar discovered by Anthony Wesley to the lower left. — Jupiter as imaged by Michael Phillips on July 25th, 2009.

Jupiter is a happening place in the solar system. While bashful Mars only puts on a good show once every two year opposition period, and inner worlds such as Mercury and Venus yield no surface details to backyard observers at all, the cloud tops of Jupiter display a wealth of changing detail in even modest backyard telescopes.

And this month is a great time to start observing Jupiter, as the largest planet in our solar system just passed opposition on January 5^th. Recently, veteran astrophotographer Michael Phillips amazed us here at Universe Today once again with a stunning time-lapse sequence of Jupiter and its moons Ganymede and Io. Now, he’s outdone himself with a new full rotation compilation of the gas giant planet.

The capture is simply mesmerizing to sit and watch. At 9.9 hours, Jupiter has the fastest rotational period of any planet in our solar system. In fact, with Jupiter currently visible low to the east at sunset, it’s possible to follow it through one rotation in the span of a single long January winter night.

We caught up with Michael recently and asked him about this amazing capture. The sequence was actually accomplished over the span of five successive evenings. This made it challenging to stitch together using a sophisticated program known as WINJupos.

“While this is possible on a long winter night when it is darker longer, I typically find it easier to do over multiple nights than one long sleepless night,” Michael told Universe Today. “If you wait too many days between observations, the features will change significantly, and then two nights will not match up clearly. The seams that result from using multiple nights are tricky to stick together. I created multiple non-overlapping seams and tried to blend them out against one another as layers in my image editing software. The result is smoother, but not quite the same as a single observation.”

A 14” f/4.5 Newtonian reflecting telescope was used for the captures. “Similar weather conditions and camera settings help quite a bit to make the multiple nights’ segments match up better,” Michael noted. “Keeping the same settings, using the same location away from my house in the corner of the yard (to reduce local atmospheric turbulence) night after night gives consistent results after removing the variability of the weather.”

Planetary photography also requires special considerations prior to imaging, such as getting Jupiter high enough in the sky and at specific longitudes to get full coverage in the rotation sequence.

“I try to consider the local weather patterns and atmospheric stability (seeing), but in reality, I pushed myself to get out as much and often as I could,” Michael told Universe Today. “Typically, I try to wait until Jupiter is at the highest in the sky, as the result is looking through less atmosphere and thus more stable conditions. Sometimes, the planets jiggle around and you just want to scream ‘SIT STILL!’ Basically around the time of opposition I go out as often as it’s clear, as those are opportunities that you don’t get back again until next year.”

Jupiter reaches opposition just over once every 13 months, moving roughly one constellation eastward each time. 2013 was an “oppositionless” year for Jupiter, which won’t occur again until 2025. Michael also notes that from his observing location at 35 degrees north latitude, Jupiter currently peaks at an altitude of 77 degrees above the horizon when it transits the local meridian. “I wasn’t going to squander it waiting for perfect conditions!”

In fact, Jupiter is currently in a region in the astronomical constellation of Gemini that will be occupied by the Sun in just over five months time during the June Solstice. Currently at a declination of around 22 degrees 45’ north, Jupiter won’t appear this high in the northern sky near opposition again until 2026.

It’s also amazing to consider the kind of results that backyard observers like Michael Phillips are now routinely accomplishing. It’s an interesting exercise to compare Michael’s capture side-by-side with a sequence captured by NASA’s New Horizons spacecraft during its 2006 flyby of Jupiter:

Both sequences capture a wealth of detail, including the enormous Great Red Spot, the Northern and Southern Equatorial Belts, and numerous white spots and smaller swirls and eddies in the Jovian atmosphere.

To date, six spacecraft (Pioneer 10 and 11, Voyagers 1 and 2, New Horizons and Cassini) have made flybys of Jupiter, and one, Galileo, orbited the planet until its demise in 2003. Juno is the next in this legacy, and will be inserted into orbit around Jupiter in July 2016.

Now is the time to get out and observe and image Jupiter and its moons, as it moves higher into the sky on successive evenings towards eastern quadrature on April 1st, 2014.

Congrats to Michael Phillips on an amazing sequence!

2014 is the Year of Orion.

Orion is NASA’s next human spaceflight vehicle destined for astronaut voyages beyond Earth and will launch for the first time later this year on its inaugural test flight from Cape Canaveral, Florida.

The space agency is rapidly pressing forward with efforts to finish building the Orion crew module slated for lift off this Fall on the unmanned Exploration Flight Test – 1 (EFT-1) mission.

NASA announced today that construction of the service module section is now complete.

The Orion module stack is comprised of three main elements – the Launch Abort System (LAS) on top, the crew module (CM) in the middle and the service module (SM) on the bottom.

With the completion of the service module, two thirds of the Orion EFT-1 mission stack are now compete.

LAS assembly was finalized in December.

The crew module is in the final stages of construction and completion is due by early spring.

Orion is being manufactured at NASA’s Kennedy Space Center (KSC) inside a specially renovated high bay in the Operations and Checkout Building (O&C).

“We are making steady progress towards the launch in the fall,” said NASA Administrator Charles Bolden at a media briefing back dropped by the Orion service module inside the O&C facility.

“It’s very exciting because it signals we are almost there getting back to deep space and going much more distant than where we are operating in low Earth orbit at the ISS.”

“And I’m very excited for the young people who will have an opportunity to fly Orion,” Bolden told me in the O&C.

Lockheed Martin is the prime contractor for Orion under terms of a contract from NASA.

Orion is NASA’s first spaceship designed to carry human crews on long duration flights to deep space destinations beyond low Earth orbit, such as asteroids, the Moon, Mars and beyond.

The inaugural flight of Orion on the unmanned Exploration Flight Test – 1 (EFT-1) mission is on schedule to blast off from the Florida Space Coast in mid September 2014 atop a Delta 4 Heavy booster, Scott Wilson, NASA’s Orion Manager of Production Operations at KSC, told Universe Today during a recent interview at KSC.

Orion is currently under development as NASA’s next generation human rated vehicle to replace the now retired space shuttle.

Concurrently, NASA’s commercial crew initiative is fostering the development of commercial space taxi’s to ferry US astronauts to low Earth orbit and the International Space Station (ISS).

Get the details in my interview with SpaceX CEO Elon Musk about his firm’s Dragon ‘space taxi’ launching aboard the SpaceX upgraded Falcon 9 booster – here.

The two-orbit, four- hour EFT-1 flight will lift the Orion spacecraft and its attached second stage to an orbital altitude of 3,600 miles, about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years.

The crew module rests atop the service module, similar to the Apollo Moon landing program architecture.

The SM provides in-space power, propulsion capability, attitude control, thermal control, water and air for the astronauts.

For the EFT-1 flight, the SM is not fully outfitted. It is a structural representation simulating the exact size and mass.

In a significant difference from Apollo, Orion is equipped with a trio of massive fairings that encase the SM and support half the weight of the crew module and the launch abort system during launch and ascent. The purpose is to improve performance by saving weight from the service module, thus maximizing the vehicles size and capability in space.

All three fairings are jettisoned at an altitude of 100 miles up when they are no longer need to support the stack.

On the next Orion flight in 2017, the service module will be manufactured built by the European Space Agency (ESA).

“When we go to deep space we are not going alone. It will be a true international effort including the European Space Agency to build the service module,” said Bolden.

The new SM will be based on components from ESA’s Automated Transfer Vehicle (ATV) which is an unmanned resupply spacecraft used to deliver cargo to the ISS.

A key upcoming activity for the CM is installation of the thermal protection system, including the heat shield.

The heat shield is the largest one ever built. It arrived at KSC last month loaded inside NASA’s Super Guppy aircraft while I observed. Read my story – here.

The 2014 EFT-1 test flight was only enabled by the extremely busy and productive year of work in 2013 by the Orion EFT-1 team.

“There were many significant Orion assembly events ongoing on 2013” said Larry Price, Orion deputy program manager at Lockheed Martin, in an interview with Universe Today at Lockheed Martin Space Systems in Denver.

“This includes the heat shield construction and attachment, power on, installing the plumbing for the environmental and reaction control system, completely outfitting the crew module, attached the tiles and building the service module which finally leads to mating the crew and service modules (CM & SM) in early 2014,” Price told me.

Orion was originally planned to send American astronauts back to Moon – until Project Constellation was cancelled by the Obama Administration.

Now with Orion moving forward and China’s Yutu rover trundling spectacularly across the Moon, one question is which country will next land humans on the Moon – America or China?

Stay tuned here for Ken’s continuing Orion, Chang’e-3, Orbital Sciences, SpaceX, commercial space, LADEE, Mars and more news.

Herschel Discovers Water Vapor Spewing from Ceres

With the Dawn spacecraft now heading towards the dwarf planet/asteroid Ceres, the mission has suddenly gotten even more intriguing. The Herschel space observatory has discovered water vapor around Ceres, and the vapor could be emanating from water plumes — much like those that are on Saturn’s moon Enceladus – or it could be from cryovolcanism from geysers or icy volcano.

“This is the first time water vapor has been unequivocally detected on Ceres or any other object in the asteroid belt and provides proof that Ceres has an icy surface and an atmosphere,” said Michael Küppers of ESA in Spain, lead author of a paper in the journal Nature.

Ceres might be considered to have a bit of an identity crisis, and this new discovery might complicate things even more. When it was discovered in 1801, astronomers thought it was a planet orbiting between Mars and Jupiter. Later, other bodies with similar orbits were found, marking the discovery of our Solar System’s main belt of asteroids.

Ceres laid claim as the largest asteroid in our Solar System, but in 2006, the International Astronomical Union reclassified Ceres as a dwarf planet because of its large size.

But now, could Ceres also have comet-like attributes? Herschel scientists say the most straightforward explanation of the water vapor production is through sublimation, where ice is warmed and transformed directly into gas, dragging the surface dust with it, and exposing fresh ice underneath to sustain the process. This is how comets work.

Ceres is roughly 950 kilometers (590 miles) in diameter. The best guess on Ceres composition is that it is layered, perhaps with a rocky core and an icy outer mantle. Ice had been theorized to exist on Ceres but had not been detected conclusively, until now.

Herschel used its far-infrared vision with the HIFI instrument to see a clear spectral signature of the water vapor. But, interestingly, Herschel did not see water vapor every time it looked. There were variations in the water signal during the dwarf planet’s 9-hour rotation period. The telescope spied water vapor four different times, on one occasion there was no signature. The astronomers deduced that almost all of the water vapor was seen to be coming from just two spots on the surface.

Although Herschel was not able to make a resolved image of Ceres, the team was able to derive the distribution of water sources on the surface.

“We estimate that approximately 6 kg of water vapour is being produced per second, requiring only a tiny fraction of Ceres to be covered by water ice, which links nicely to the two localised surface features we have observed,” says Laurence O’Rourke, Principal Investigator for the Herschel asteroid and comet observation programme called MACH-11, and second author on the paper.

The two emitting regions are about 5% darker than the average on Ceres. Since darker regions are able to absorb more sunlight, they are then likely the warmest regions, resulting in a more efficient sublimation of small reservoirs of water ice, the team said.

They added that this new finding could have significant implications for our understanding of the evolution of the Solar System.

“Herschel’s discovery of water vapour outgassing from Ceres gives us new information on how water is distributed in the Solar System,” said Göran Pilbratt, ESA’s Herschel Project Scientist. “Since Ceres constitutes about one fifth of the total mass of asteroid belt, this finding is important not only for the study of small Solar System bodies in general, but also for learning more about the origin of water on Earth.”

Dawn is scheduled to arrive at Ceres in the spring of 2015 after spending more than a year orbiting the large asteroid Vesta. Dawn will give us the closest look ever at Ceres surface and provide more insight into this latest finding.

“We’ve got a spacecraft on the way to Ceres, so we don’t have to wait long before getting more context on this intriguing result, right from the source itself,” said Carol Raymond, the deputy principal investigator for Dawn. “Dawn will map the geology and chemistry of the surface in high resolution, revealing the processes that drive the outgassing activity.”
